' "HAND FAN. r

if This invention relates to a hand fan prowhen it is desired to videdwith a suitable motor for operatingthe fan blades and preferably thedevice is of the small type so that it can be "readily carriedinthepocket for convenient access.

One of the objects of the invention is to provide a hand fan with aspring motor which be conveniently 'woun'd up from time to time and thenthe spring releasedso as to rotate the fan blades when a person desiresto, cool off. Another object is to provide a hand'fan of the type justmentioned with alongitudinal movable handle which may be shoved inwardlyin order to wind up the motor and which-may be slid outwardly permit themotor to rotate the fan blades. v

, Other objects of the invention are to provide a convenient motoroperated pocket fan cost for a device of this kind is reducedto aminimum, which may be readily operated from'tim-eto time, as desired. bya rotation of the handle whereby the entire device may be supported inone hand, and which is preferably constructed of metal so as to renderit durable and to enable it to be made attractive by the use ofdifferent shapes and designs. 7 a

These being among the various objects of the present invention, thesameconsists of certain features of construction and combinations ofparts tobe hereinafter described and then'claimed with reference to theaccompanying drawings illustrating one'embodiment of the invention,inwhich:

an opening at the back through whiohj'the various parts'of, the motormay be introduced intothe casing; The casing 10 may be of" any desiredshape and may be ornamented and may be attractive in any desired manner.A mounting plate 11 is provided for supporting the elements of the geartrain of the motor and also the'coiled winding spring 12. This windingspring whichcis ablyv one which requires repeated winding for temporaryoperation of the motor, although it is obvious that the winding springand associated parts may be" made for: a longer period of rotationof thefan blades,

invention a different tvpe of motorrnay be employed winch may bereleased fromftime The primary gearl? is fixed on the drivingshaft 13.while secondarygears 18, 19

are respectively fixed on shaftsi14,i15.,.-A

bevel pinion 20 is fixed on the driving shaft 13.. while pinions 21. 222am respectively fixed on shafts 14. 15, 16. the said gears 17, 18, '19and the pinions 21. 22 and 23 being meshed in well knownmannerlfortransmittingthe desired power from the driving shaft13 to theultimately driven shaft'lfi.

The winding and operatin'g' spring :12is1 "securedat its outer end to apin 24' sup ported, from the mounting plate 11, and the inner end ofsaid spring is secured' to. the driving" shaft 13, so that this type ofpower meansfor the motor may be wound up from 1 timeto time bynthe shaft13.:and then re-' leased to expand and exert its spring power.

7 p Also fixed on winding shaft 13 is a ratchet 10 wheel 25 'havingbeveled' teeth which are engaged-one at a time by a'pawlor dog2 6whichis pivotedto the large "gear 17 and whichis impelled to engage theratchetteeth bymeans of a bowed spring 27 which'is held 5 fast at oneend on said gear 17. and ,at its free end is connected with the pawl26,-'ll 1ej 1n functioniof this pawl and ratchet device spring motors iswell known.

.70 and that even in some aspects of the present These parts now beingdescribed are more I30 clearly shown in Figures 4, Errand The manner ofassemblingtheplate lland the gear train of the motor with and into thecasing 10 will be readily understood by those skilled in spring motors.The shaft 13 turns in a bearing in the mounting plate 11, while theshafts 1st. 15 and 16 are stepped in hearings in said plate. The shaft16 and its pinion 23 are first mounted in the bearing of the front ofthe casing, and then the shafts, gears and winding spring mounted on theplate ll are passed through the rear opening of the casing 10 and theshafts 13, ll, 15 finally caused to engage the step bearings of thefront of the casing. Of course the parts may be assembled in other ways.

The mounting plate 11 is preferable rigid ly secured in the casing 10 inthe following manner. Plate 11 is provided with an outwardly turnedflange 28 which frictionally engages with the inner wall of the casing,and against the edge of said flange there is placed a back plate 29which constitutes the back of the casing. When the back plate 29 hasbeen introduced, the rear edge of the casing 10 is upset over the backplate 29 in the form of a flange 30. The flange 30 will thus hold theinterior parts of the casing 10 in place. Other means may of course beadopted for securing the mounting plate 11 within the casing.

Inasmuch as the hand fan of the present invention is preferably ofpocket size. the fan blades 31, 32 fixed on the driven shaft 16projecting from the casing, are of such size that they may be adaptedfor being folded in order to more readily go into ones pocket.Preferably to this end the fan blade 31 is composed of two sectionsconnected by a hinge 33, so that the outer section may be folded againstthe fan blade It will be seen that the spring motor is of such type thatthe fan blades may take the position shown in Figures 2 and 3 so thatthe entire fan device may be readily slipped into the pocket of the onewho wishes to make use of. the fan. It is preferred to make use ofextremely convenient and simple means for winding up from time to timethe spring of the preferred motor which has been described.

To this end the casing 10 is provided with an opening 34 which islocated adjacent the driving shaft 13 and around said opening thereextends outwardly from the edge of the casing a guide sleeve This sleeveextends at right angles to the winding shaft 13. A handle 36 is providedwhich is at least of a length so as to be conveniently grasped by thehand of the user, and this handle is preferably tubular, as shown insection in Fig. 2 and into its inner extrei'nity there is rigidly fixeda plug 37. There is a stem 38 rigidly secured in the plug 37 so that itsaxis and the axis of the handle are coincident, and upon the inner endof the stem 38 there is fixed a winding bevel pinion 39. Pinion 39 isadapted for engagement with bevel pinion 20 on the winding shaft 13. Thehandle 36 provided with a reduced end portion -10 joined with the mainbody of the handle by an annular shoulder 41. The reduced portion it]snugly yet loosely fits into the guide sleeve 37 so as to locate thepinion 3-) in juxtaposition to the bevel pinion 20.

Preferably the handle 36 is slidable with respect to the guide sleeve35, into which it telescopes, and the reduced portion it) is providedwith an annular groove 4;, as shown clearly in Figs. tand (i. Theopposite side walls 43, a l of groove 42 provide annular abutmentshoulders. and between them there projects a stop pin :5 which isrigidly fixed to the guide sleeve The abutnu-nt shoulders 43 and 44- andthe stop pin to constitute means for limiting the extent of inward andoutward sliding movement of the handle 36. lVhen the handle is pushedin, the winding pinion St) is brought in mesh with the bevel pinion 20,thereby to permit of the winding up of the. spring 12 when the handle 36is rotated. It will be seen that the annular groove 4-2 permits ot' therotation of the handle when it is in its inward position. hen the handle36 is pulled outwardly, the pinion 239 unmeshcd from pinion 20 and thecoiled spring 1:3 released, thereby operating the gear train of themotor and rapidly rotating the fan lades 31, 32 at an increased speedover the large gear 17. Thus when the pinion I3!) is released, the user,still grasping the handle so, may grasp not only the handle but thesleeve so as to hold the casing lti stationau and the user may then talc the benctit of the breeze which is caustd by the fans 31 and 32.

Preferably the parts of the described device are made up of metal. thecasing and its parts and the handle and fan blades being of sheet metal.although it is obvious that various features of the device may be madeof other material. As viewed from the outside the device is of extremesimplicity and lends itself to any desirable design, eoniignration andornamentation and may be readily cleaned by the user by means of apocket handkerchief. When in pocket size, as is preferred. the device isextremely com pactand is very cilicient for the desired cooling ofl"purposes. It is obvious that the described and illustrated device iscapable of more or less modification without departing from the spiritof the invemion as expressed by the scope of the appended claims.
